Improvement in automatic gates



0. P CLINTON Automatic Gate.

Patented July 13 1875.

To all whom it may concern Improvements in Carriage- Gates, of which the following is a description:

the arrangement of a series of pulleys, levers,

closed without the necessity ot' the occupants or driver of a carriage requiring to pass such gate having to alight for the purpose of opening the same, the nature of which will be fully explained by reference to the accompanying drawing, which forms part ot' this specification.

nary construction, except that at its rear end it is provided with a box or receiver, B, for the reception of stone or other material to bal` ance the'weight of the longer arm of the gate. C is the heelpost affixed at one side ot' the roadway, and D is the head-post aixed at the opposite side of the road. affixed to the heel-post C, with capability of adjustment vertically by means ot' bolts a, passing through slots a', secured in the post O. To this plank O is connected one leaf of leaf of each hinge being connected to a vertical post or standard, E, affixed to the gate A cross bar or arm, F, is connected, extending the gate A. At each end the arm F is provided w-ith a Y-shaped lever, c, pivoted the ends d of a bit'urcated chain, d, is attached,

ing conducted' around a pulley, e, turning freely in bearings carried by the arm F, and

tached, the lower end of which is connected to v'lr'rnN'r Grrron ORSON I. CLINTON, OF MENASHA, WISCONSIN.

and chains supported upon posts, whereby a carriage-gate may be readily opened and A represents the gate, which is of the ordi- O is a plank each of the hinges ot' the gate A, the other at about one-third of its length from the heel end. To the upper end of the standard E a diagonally right and leftot the center line ot' centrally between its arms 1 1 and 2. To each of the arms 1 1 of the levers c one of the main portion d of each of the chains beconnected to one end of an L-lever, f, pivoted to a bracketor extension from the upper end of the standard E. To the opposite arm of the lever f the upper end of a wire, g, is atone arm of another L,-lever,f, the opposite arm ot' which is, by means of another wire, g',

connected to the rear end of a sliding latchbolt, h, which is kept forward by means of a spring, Ii, so as to engage with a catch, j, carried by the head-post. G G are posts or uprights erected on each side of the gate, and at a considerable distance from the same, each of which is provided with an arm or bracket, G', extending over the roadway. To

each ot these arms G two pairs ot' pulleys or4 guides, 3 3 4 4, are affixed, for the purpose ot' supporting and guiding the chains or ropes H H1, one end of each of the cords H H being connected to the arm 2 of one' of the levers c,

while the ends of the other pair, H1 H1, are connected to the arm 2 ot' the lever c at the opposite end of the cross-bar F. H2 H2 are weights attached to the opposite end of each of the cords or chains H H1, as shown in the drawing, which serve both to keep the chains taut, and also as handles for the same.

The operation of my apparatus is as follows: On approaching the gate when closed, the shorter vchain is pulled, (which, if approaching from the right, will be the chain H, and it' from the left the chain H,) thereby iirst turning the lever c on its axis, and, by means. of the levers f f and rods g g releasing the boltlz.. The tension on the cord being continued, the arm F is swung around, and with it the gate A, therebyleaving the road open and free for the passage ot' vehicles or passengers. After having passed the gateway, and it is desired to close the gate, all that is necessary .is to pull the shorter chain of the post G you next approach, when the reverse motion of the lever F will be effected, and the gate closed. Having thus described my invention, I would have it understood that I lay noclaim lseparately to a weighted or balanced gate, as

lspecifications ot' the rejected application of A.
